Answer:
The probability that Joe's stock will go up and he will win in the lottery is 0.00005.
Step-by-step explanation:
Let the events be denoted as:
<em>X</em> = the stock goes up
<em>Y</em> = Joe wins the lottery
Given:
P (X) = 0.50
P (Y) = 0.0001
The events of the stock going up is not dependent on the the event of Joe winning the lottery.
So the events <em>X</em> and <em>Y</em> are independent of each other.
Independent events are those events that can occur together at the same time.
The joint probability of two independent events <em>A</em> and <em>B </em>is,
Compute the value of P (<em>X ∩ Y</em>) as follows:
Thus, the probability that Joe's stock will go up and he will win in the lottery is 0.00005.
Answer:
The given equation is
Which represents an elipse.
To find its elements, we need to divide the equation by 100
Where and
. Remember that the greatest denominator is
, and the least is
. So, we extract the square root on each equation.
and
.
In a elipse, we have a major axis and a minor axis. In this case, the major axis is vertical and the minor axis is horizontal, that means this is a vertical elipse.
The length of the major axis is .
The length of the minor axis is .
The vertices are and
.
Now, the main parameters of an elipse are related by
, which we are gonna use to find
, the parameter of the focus.
So, the coordinates of each focus are and
The eccentricity of a elipse is defined
The latus rectum is defined
Finally, the graph of the elipse is attached.
